INCUBATOR-HEATING SYSTEM.

Application filed August 7, 1920. Serial No. 402,010.

To aZZ whom it may concern Be it known that I, JOHN D. J owns, a citi zen of the United States, residing at Heltonville, in the county of Lawrence and State of Indiana, have invented certain new and useful Improvements in Incubator- Heating Systems, of which'the following is a specification, reference being had to the accompanying drawings.

This invention relates to a heating sysj tem for incubators and has for its object to' provide a heating system capable of evenly distributing the heat to all parts of the incubator.

Another object is to provide a heating system of this character including a radiator, the various parts of "which are simultaneously supplied with hot water received from a novel form of boiler.

Another object is to provide a heating system of this character including an inlet conduit which gradually increases in size after leaving the-boiler so as to prevent resistance in the discharging operation of water from the boiler so. that no heat is wastedand at the same time the heat is assisted in its radiation.

Another object is to provide a heating system of this character including a reservoir formed from a single endless conduit having tapering ends which merge into an outlet and a tapering inlet conduit which extends longitudinally of the single conduit and is disposed in the plane of said conduit so that the device may be conveniently supported within the incubator chamber.

Another object is to provide a system of this character including a novel form of boiler which is provided with a damper directly above the heating means, the damper being automatically regulated so that the proper temperature is maintained at all times.

With the above and other objects in view, the invention consists in the improved construction and arrangement of parts, to be hereinafter more particularly described, fully claimed and illustrated in the accom panying drawings, in which:

Figure 1 is a fragmentary vertical elevation of an incubator with the invention applied. a portion of the heating conduits being shown in section,

Fig. 2 is a top plan view of the entire heating system, and i 1 Fig. 3 is a vertical sectional view of the boiler.

Referring to the drawings, 5 designates a radiator, said radiator consisting of an endless conduit constructed to conform to the interior dimensionsof an incubator chamber. In the present instance, it is illustrated as rectangular, the end portions 6 of the radiator tapering from their extremities, said extremlties merging with a tapering outlet conduit 7. In order to supply the radiator 5 with hot water, an inlet conduit 8 is provided, said conduit being tapered longitudinally thereof and having its large end 9 connected to and communicating with the portion of the radiator 5 remote from the outlet conduit 7. The small end portion lOextends beyond the end portions 6 of the radiator. To permit hot water to reach the radiator rapidly, I provide a' pair of branch Specification of Letters Patent. P t t d Deg, 13, 1921 conduits 11, said conduits intersecting the .inlet conduit 8 at its intermediate portion,

each of the conduits 11 extending in opposite directions and adapted to communicate with the radiator 5 between the intermediate portion of said radiator and its ends. In this way water discharged from the end of the inlet member Sinto the radiator is caused to circulate by the discharge of water into the radiator through the branch con duits 11, as the water discharged by the branch conduits substantially creates a suction which serves to circulate the water and thereby cause rapid return of the cooled -waterv to the boiler. It will be noted that the end portion 9 of the'inlet conduit 8 corresponds in diameter to the diameter of the intermediate portion of the radiator so that while the water is circulating through the inlet member the heat is permitted at the same time to radiate, and when the water reaches the radiator, it is not necessary for the eggs. n this Way, the heat is applied according to nature and in view of the novel formation of the inlet and supply conduits as well as the formation of the endless radiator 5, the heat is evenly distributed and regulated so that danger of one portion of the chamber receiving more heat than the other portion is eliminated.

To properly regulate the temperature of the'water supplieo to the radiator, 1 provide a novel form of boiler 12 which is supported by the heating means such as the lamp B, through the medium of a chimney or outlet 12 which extends through the boiler. The boiler 12 has its bottom and side portions inclosed by means of a packet 13, said jacket being disposed in spaced relation to the boiler. The upper portion of the jacket is closed by a plate 13. Formed centrally of the top let of the boiler is an opening 15 in which an oscillating valve or damper 16 is mounted, said damper being movable on a rod 17 which extends through the upper end of the chimney 12 The end 19 ofthe rod is disposed in angular relation thereto and. provided with a weight.

20, the remaining portion 18 of the rod extending beyond the side of the jacket and journaled in a bracket 21. The end 22 of the rod is disposed in right angular relation thereto and in the opposite direction to the end 19, the end 21 being connected to the usual automatic regulating means 23 of the incubator. In this way. when said means is operated to regulate the temperature, the damper 16 is likewise operated so as to permit the escape of heat, the weight 20 assisting in the regulation of the damper upon reversed movement or operation of the regulating means 23. An outlet opening 24 is provided at the top of the boiler to permit the escape of steam, while a drain cook 25 is carried by the lower portion of the boiler to permit the water to be drawn therefrom. I

The end portion 10 of the inlet conduit 8 extends through the jacket 13 and into the upper portion of the boiler while the end portion of the outlet conduit 7 extends through the jacket into the lower portion of the boiler. It will be noted that the portions of the inlet conduit 8 and outlet conduit 7 entering the boiler, are similar in and compact in form, provides an even discharge of heat through the incubator chamber in the natural manner and is supplied with water from a novel boiler which is controlled by the usual and well known thermostatic means common to incubators. In addition to this, it may be readily applied to the variousstyles of incubators now in use.

What I claim is 2- A heater for incubators comprising a conduit member having tapered end portions, said member being formed into a frame adapted to engage the inner walls of an incubator, an inlet conduit extending. transversely of the tapered end portions of the frame, one end portion of said inlet conduit being larger'in diameter than the opposite end portion, said large end portion being connected to one end portion of the frame, branch conduits intersecting the-intermediate portion of each side of the frame and the inlet conduit, whereby water discharged into the frame through the large end portion of the inlet conduit is caused-to circulate by the discharge of water from the branch conduits into the water disposed in the side portions of the frame, a tapered outlet member intersecting the tapered end portions of the frame, and means supplying heated water to the heater. I

In testimony whereof I hereunto afiix my signature.
